Letters Patent No. 101,493, dated April 5, 12870.

DPROVEMENT IN WALKING-BEAM AND STICKER-ROD CONNECTIONS FOR DEEP WELLS.

The Schedule referred to in these Letters Patent and making part of theSame- To all whom it ma/y concern:

Be it known that I, MARcnLLUs A. MORSE, of the city of Titusville, inthe county of Crawford and State of Pennsylvania, have invented a newand useful improved Connection of Sucker-rods and lValking-beam forOperating Deep Wells; and I do hereby declare the following to be afull, clear, and exl act description thereof, reference' being had tothe accompanying drawing making a part of this speciaction, in which-Figure l is 4a front or end view of my improve ment;

Figure 2 is a side elevation thereof; v

Figure 3 is a sectional view of the connecting-v joint.;

Figure 4 is a perspective view of the gib or pressure-block; and

Figure 5 is a perspective view of the set-screw.

Like letters of reference indicate like parts in each.

My invention, while useful in operating deep wells generally, is ofespecial value in the pumping of oil-` wells, since, to secure thegreatest possible yield of oil, it is necessary that the piston becarefully ad-d justed in the working-barrel, at the required depth inthe well, with especial reference to the location of the 'sand oroil-producing rock.

The sucker-rods extend from the piston up to the mouth of the well, andby a rod, which is jointed -to a stirrup on the end of the walking-beam,are connected with the latter.

Such connection, hitherto in general use, provides no means by which thepiston can be suiiiciently adjusted, so as to operate at a point higheror lower.

My invention relates to an improved joint for effecting such anadjustment; and.

The nature of it consists in combining a solid mortised head-piece,having cylindrical trunnions, with a concave-ended setscrew, for holdingau adjustable connecting-rod, which passes through the mortise in thehead-piece, at any desired point of adjustment.

Also, in combining a'gib or pressure-block with an adjustableconnecting-rod, mortised head-piece, and set-screw.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and mode of operation.

The walking-beam A is slot-ted at its forward end, and on the upper faceof each of the bifurcations A', a concave seat is made for thecylindrical trunnions a' of the head-pece a.

This latter is a solid block of metal, except that it has a mortise, c,extending through it, through which passes the connecting-rod b, thelower end vof which is to be. jointed to the sucker-rods.

Also, a tapped hole is made in one side of the head-piece a at, ornearly at, right angles to the di-y rection of the mortise c, in which aset-screw, d, operates, the parts being so arranged that the inner endof the set-screw d shall bear against the connecting-rod b, or againsta'gib or pressure-block, e, inserted in the mortise c hetweenthe two.

This pressure-block may be of any desired length, its inner face planeor corrugated, as also the tace ot' the mortise c opposite thereto, ifso desired, the' object being, by turning the screw d tightly up againstthe block e', to produce so Vfirm a bite on the rod b that it cannotslip, even under the immense load that has to be raised with each upwardstroke of the walking-beam. v

The block e may, however, be dispensed with, and a suiiciently securebite be obtained by making the inner` end of the screw d concave orcup-shaped, as as d.

Then, when it is screwed well up against the rod l, the edges of theconcave end will take so secure a bite on the rod b that it'will be heldat any desired point of adjustment.

The concave-ended set-screw may, however, if so desired, beadvantageously used with the pressureblock e.-

With .the devices described, it is but a moments work to raise or lower.the rod bin the mortise c, nothing being nesessary thereto except toloosen and tighten the screw d, which can be done with a wrench.

For convenience in holding the block e in place while the adjustment ofthe rod bis being effected, its rear face may be notched or rabbeted, asshown.

As an improved mode of attaching the head-piece a to the walking-beam, Ihinge to it a cap, f, also slotted at its forward end, and on the underside of each bifurcation f make a concave seat, g, so that when the capis closed down, as in fig. 2, the trunnions a. will play therein, aswell as in the seat g ou the walking-beam.

A bolt his fixed in the body ofthe beam, having a screw-thread on itsupper end.

A hole is made in the cap, through which the holt h projects when thecap is down.

To hold the cap down, and so keep the head-'piece a, in place, I place across-bar, i, which is perforated at about its middle point, for thepurpose, and turn down onto it a threaded nut, t", being careful,however, not to screw it down so tightly as to make the frictionon thetrunnions a too great.

The devices described are then easily taken out for repairs, or forother-purposes, and as easily replaced, and while in place are securelyheld.

They are simple in construction, cheap, and durable.
